Hike Through Rock Creek Park

This is primarily a dirt trail, which is pretty rare and fantastic for hiking and trail-running. Depending on where you exactly start, it's roughly 4.5 miles, so it's a pretty moderate hike/ run or almost 10miles if you do the out and back. There are also a ton of other paths, so you can easily add on extra miles if you want to or get on the Valley Trail if you want to make it a super loop.
